DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0023] The following descriptions are of exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.

[0024] Referring to FIGS. 1, 1A, 2 and 3, a preferred embodiment of the present invention is comprised of a suitcase 10. Wherein, multiple fixed rods 11 detachable to a pull rod frame 20 are provided on the back of the suitcase 10. Those fixed rods 11 can be respectively arranged in pairs laterally and vertically disposed and corresponding to each other in each pair while a retractable pull rod 21 is provided on the pull rod frame 20. A catch 22, as illustrated in FIGS. 4A, 4B and 4C, is provided over the pull rod frame 20 close to where the pull rod 21 is pulled out, and is fixed with a catch holder 23 provided at where below the pull rod frame 20 to the fixed rod 11. Whereas the means for attaching the pull rod frame 20 to the fixed rod 11 is a prior art, it will not be described herein. In the present invention, the location of the catch 22, originally provided at where below the pull rod frame 20, is changed to close to where the pull rod 21 is pulled out.

[0025] Now referring to FIGS. 5 and 6, if the pull rod frame 20 is attached to the pair of fixed rods 11 laterally corresponding to each other on the back of the suitcase 10, the suitcase 10 is vertically attached to the pull rod frame 20; and alternatively if the pull rod frame 20 is attached to another pair of fixed rods 11 vertically corresponding to each other on the back of the suitcase 10, the suitcase 10 is laterally attached to the pull rod frame 20 as preferred by the user. Whereas the catch 22 is provided close to where the pull rod 20 is pulled out, the user after having attached the catch 22 to the fixed rod 11 at where the pull rod 21 is pulled out, is able to pull out the pull rod 21 without interruption, or after retracing the pull rod 21, to operate the catch 22 to detach the pull rod frame 20 from the suitcase 10.

[0026] As illustrated in FIGS. 1, 7A, 7B and 7C, the suitcase 10 is generally comprised of a front panel 12, a back panel 13, and two outer side panels 14. A lower covering panel 16 and an upper covering panel 15 are respectively extending from the front panel 12 and the back panel 13 to cover up the opening of the suitcase 10. A porch 121 adapted with a lock 122 is provided on the front panel 12 of the suitcase 10. A thicker vibration absorbing cotton 141 is provided in each of both outer side panels 14 to protect the suitcase 10, or both outer side panels 14 may be made of aluminum to reduce the weight of the suitcase 10. The overlapped upper covering panel 15 and the lower covering panel 16 provided at the opening of the suitcase 10 are made of same size and shape to give better sealing effects and more attractive appearance of the suitcase 10. A handle 161 is provided on the surface of the lower covering panel 16 and a gap 151 in size larger than that of the handle 161 is provided on the surface of the upper covering panel so that the handle 161 will not become an obstacle in opening or closing the upper covering panel 15. A pair of locks 152 with comer rounded to prevent cutting the user is provided at the front edge of the upper covering panel I5. A resilient stick 101 (e.g. rubber) 101 is protruded from the peripheral of the opening of the suitcase 10 and a resilient channel 162 corresponding to the resilient stick 101 is provided on the inner side of the lower covering panel 16 so that when the lower covering panel 16 closes up the opening of the suitcase 10, both of the resilient stick 101 and the resilient channel 162 are tightly engaged to each other to provide waterproof effects. Once the lower covering panel 16 is opened up, the resilient stick 101 prevents seepage of water containment into the suitcase 10 while the resilient channel 162 stops seepage of water containment from the outer surface of the lower covering panel 16 while guiding the water containment to leave the suitcase 10. A mesh porch 164 adapted with a zipper 163 is provided on the inner side of the lower covering panel 16.

[0027] Now referring to FIGS. 8A, 8B and 8C, the front panel 12 of the suitcase 10 is flapped so that the front panel 12 can be forthwith opened up to facilitate inspection by the customs at the airport. Wherein, a channel 162 extending from the lower covering panel 16 is provided at where the front panel 12 is attached to the outer side panel 14, and a stick 101 extending from the opening of the suitcase 1—is provided at where the outer side panel 14 is attached to the front panel 12 of the suitcase 10. Consequently, the front panel 12, the stick 101 from the outer side panel 14 and the channel 162 can be easily joined to one another to give waterproof effects, and can be easily separated from one another. To improve the support strength of the front panel 12, multiple snap locks 123 may be provided at where the front panel 12 joins the lower covering panel 16 and multiple snap rings 142 may be provided at where the front panel 12 joins the outer side panel 14; so that when the front panel 12, the outer side panel 14 are joined, those snap locks 123 can be directly locked into those snap rings 142 to prevent the front panel 12 from being separated due to improper external force. To open up the front panel 12, simply depress those snap locks 123 to disengage them from those snap rings 142.

[0028] It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.

[0029] While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
